27 Claims. (01. 229-53) v This invention relates to improvements in containers, and more particularly to a container adapted to contain ice cream and like products which maybe shipped in compact knockdow condition.

The well known metal can as a packaging medium for ice cream and like bulky heavy semiliquid products has serious drawbacks since this type of packaging medium is expensive 121 first cost, heavy and cumbersome to transport, it must be collected for reuse, is unsanitary, attracts flies,

dirt and vermin, and it requires expensive washing and cleansing equipment to put the same in condition for reuse. Canisters and containers of [paperboard material possess attractive qualities as regards sanitation,'but heretofore have presented certain objections which have prevented their adoption. To permit the container to be discarded after the first use, it must be economical to produce; it must also be strong and sturdy to withstand rough handling; convenient to grasp, and carry, substantially liquid-tight so as to hold the liquid cream prior to freezing; adapted to withstand moisture without weakening or col lapsing; free from any harmful or contaminating influences on the contents; offer full protection to the contents, and so made as to be economical to transport and store. Containers of flbreboard heretofore made to replace the well known metal can are very weak and possess a decided tendency .toward inward collapse. Furthermore, the bottoms often become so weakened by contact with moist floors and moist contents that they give way and break before the contents can be re- 'moved.

With the above requirements in view, it is an object of this invention to produce a container I especially adapted for the packaging of bulk ice cream and similar food products which is eminently economical, improved and advantageous over other packaging devices heretofore used.

Another object of this invention is to provide a container which may be collapsed for shipping and storage purposes but which is so reinforced as to positively prevent collapse when set up for or during use.

Another object of my invention is to provide a container heldtogether by the interlocking of the parts without the use of staples, glue or similar securing means.

Another object of this invention is to provide an improved container of generally circular, ovate or polygonal shape, having separable bottom, cover and body parts which can be either nested together or collapsed for transport and storage in either assembled or partly assembled condition and thereby effect great economy of space and facility in handling.

Another object of my invention is to provide a low cost container, which is strong and sturdy in construction, which will not weaken or deteriorate through contact 'with moisture, which can be easily and quickly made by unskilled labor with inexpensive equipment and which can be assembled complete eitherby the maker or the user, which is leakproof for all practical purposes, which is sanitary and attractive in appearance and can be discarded after first use with economy.

. These and other desirable objects and advantages of the present invention'will become apparent as the disclosure proceeds.

Certain preferred embodiments of the invention are disclosed in the accompanying drawings for purposes of example only, for, since the underlying concepts may be embodied in otherspecific constructions, it is not intended to be limited to the ones here shown, except as such limitations are clearly imposed by the appended claims.

Fig. 10 is a perspective view of another container presented to illustrate another of the various shapes which containers made in accordance with the present invention may take.

Referring now in detail to the drawings, the invention will be described in particular detail with respect to a frusto-conical container. The container may comprise generally a body or barrel member B. a bottom end member E with or without a cover member C. The body or barrel portion, as shown in Figure 7, may be formed from a suitably shaped blank l provided with an outturned, depending flange or shoulder ll formed at the top thereof The flange ll may be slit or cut at spaced intervals, as at II, to provide a series of downwardly depending tabs l3 which interlock with the cover member when it is forced thereover. The bottom edge of the blank is provided with a shoulder or flange or rim which may comprise upwardly extending tongues l5 defined by the cuts H. The bottom flange or rim interlooks with the bottom end member when forced into engagement therewith. The body may'be formed from a flat blank bent to the desired shape, as shown in Figure 7 and the vertical edges abutted or overlapped and then may be held together by staples l6, by thread stitching, or other. suitable means. The body member may be also provided with a plurality of vertical score lines 11, at least one pair of which are diagonally spaced permitting collapse thereof for transport and storage purposes, as shown in Figure 9.

The bottom end member, as shown in Figures 3, 4 and 8 comprises a continuous rim or hoop formed from relatively rigid material, such as metal, the rim having a side wall portion 2| and an inwardly extending seating flange 22. A bottom piece 23 of strong, relatively stifl material, such as paperboard, rests upon the seating flange 22 and forms the bottom portion of the container. The rim portion is provided with an inwardly extending lip 24 which serves an important purpose, as will hereafter be brought out.

In assembling the container the flanged bottom end of body portion B, as shown in Figure 7, is formed into the bottom and member E and engages or interlocks with the bottom reinforcing rim 20. When the flanges or flange forming tongues l5 are not secured to the body, they expand or spring outwardly, due to their natural resiliency, and remain pressed against the inside surface of the rim portion 2| and seated under the inturned lip 24, thus firmly and permanently securing the body member to the bottom end member of the container. When so arranged the lower end l8 of the body member abuts against the bottom piece 23 holding the same in place and forming a tight joint therewith so that no part of the contents may come into contact with the metal rim. Normally, the pressure of the contents will hold the bottom flange in firm gripping engagement with the rim 20, but if desired an insert piece of slightly oversize dimensions, as shown in my application, Serial No. 600,843 filed concurrently herewith, may be inserted into the tubular body member to seat upon the bottom disc 23 pressing the body outwardly against the bottom rim.

The cover member C as shown more particularly to Figures 3, 5, 6 and 8, comprises a rim piece which is preferably made of relatively strong rigid material such as non-corroding metallic material. The rim piece comprises a side wall portion 3|, an inturned lip portion 32 at its lower edge, and an inturnedbead portion 33 at the top edge thereof. A cover piece 34, which may be made from relatively stiff, strong fibreboard material, has the peripheral edge 35 thereof fitted within and gripped by the inturned bead portion 33 to form a complete assembled cover.

After the container has been packed with the contents M, the cover member C is then telescoped over the top of the body member until the lip portion 32 clears the end of the flange i I. If the flange l l which may be slit as at l2 to form tabs I3, is unsecured to the body, the flange or tabs will then spring outwardly, due to the natural resiliency of the material, so that the ends of the flange seats within or interlocks with the lip portion 32. The cover member C is now secured in place and the goods can be shipped and stored fully protected against outside influences or unauthorized tampering. The rigid top and bottom rim pieces 20 and 30 give the container an overabundance of strength at points where the strain from the weight of the contents and rough handling is greatest. Due to the position and shape of the rim pieces, no part of the fibreboard body or bottom piece will normally contact the wet floor of the creamery, truck or storage house, whether the container stands on its top or bottom end, or rests on its side.

A common complaint against flbreboard containers when used for silky materials, such as ice cream, has been that the container side walls collapse inwardly and do not maintain their intended shape during removal of the contents. This inward collapse of the side walls makesit very inconvenient to remove the contents and creates an unsanitary condition due to the fact that the dispenser constantly contacts the top edge of the container with the ice cream and with his clothing. Furthermore, it is diflicult to maintain a tight pack of ice around the container when the side walls progressively collapse inwardly as the contents are removed.

To overcome all these deficiencies, the head portion 33 of the cover member herein disclosed is so made that the cover piece 34 can be pulled out and removed, as shown in Figure 5, when access to the contents is desired. The rim piece 30 remains as a part of the container, stiffening and reinforcing the upper'edge thereof, and positively prevents inward collapse of the side walls. The cover piece 34 may be provided with a small arcuate score 36 which may be punctured and the cover'. piece removed from the container by grasping the finger tab 31 or by inserting the finger into the aperture made by bending back the tab 31. 1

There is shown in Figure 10 a container of cylindrical shape presented to indicate the multifarious shapes'a container constructed along the principles above disclosed may take. These containers may also be made ovate or polygonal in cross section and may be provided with vertical or inclined side walls.

For convenience and economy in shipping, handling and storage, the containers may be stacked, if conical in shape, in nested relationship. If desired, the containers may be shipped to the user unassembled by nesting the body members together and nesting the body end member within the cover member, as shown in Figure 8. If preferred, the body members may be provided with two or more vertically extending scores H which will permit the body member to be collapsed and stacked as shown in Figure 9. This feature is especially advantageous when the body members are in cylindrical or only slightly conical form so as not to permit satisfactory nesting of the body members. The vertical scores produce no harmful effects, since .the rigid metallic top and bottom rim pieces 30 and 20 are fully adequate to hold the body member in proper shape when set up as part of the completed container. Desirable economies in shipping, storage and handling charges are thus effected.

If the container is shipped in knockdown condition, the body member and bottom end member may be quickly assembled by the user to provide a complete set up container as heretofore stated without special machinery or skilled labor. The body member B is preferably made of relatively stiff, strong moisture-resisting fibreboard or paperboard material, while the bottom end member E and cover member C are preferably made partly of metal and partly of flbreboard, as shown in Figures 3 and 8. The bottom piece 23, which generally takes the greater strain, may be made of heavier fibreboard material than the cover piece 34. The side wall portions 2| of the bottom rim piece 20 may be inclined, as shown in Figures and 6, to more clearly conform to the conical body, and thus afford closer nesting of the set up container. The side wall portions 3| of the top 2 rim piece 30, on the other hand, may be made vertical, with respect to the bottom piece, so that the lip portion 32 may be made deeper, thus affording a better finger grip for lifting the container either before or after the'cover piece 34 has been removed.

It is now seen that there has been provided a knockdown container which is strongly reinforced against inward collapse. The container may be made any shape desired, andthe side walls may be made of relatively thin fibreboard material or the fibreboard may be scored vertically to permit storage in flat condition without.

danger of the container breaking or collapsing under load or while in use. All parts of the container which might contact wet surfaces or floors are made of non-corroding metal which is un:- affected by moisture and dampness. The bottom and cover members are very economical to manufacture, each comprising only a simple metallic rim piece or hoop and a fibreboard discor end piece. Notwithstanding the fact that the cover member can be so economically made and is so easy to apply it serves the following purposes: 1. Provides a cover for the container; 2. Provides a foolproof seal for the contents; 3. Provides a guard which protects the container against the deteriorating effects of moisture; 4. Provides a strengthening frame which protects the container at one ofits most vulnerable points and permits the use of a lighter fibreboard body than otherwise; 5. Provides a stiff reinforcing rim preventing inward collapse of the body portion as the contents are being removed; and, 6. Provides a hand grip by means of which the container may be lifted about, before, duringand after removal of the contents. The bottom end member, in addition to providing a bottom for thc container, alsoprovides the advantages listed under (2), (3) and (4) above.

It is also seen that no securing means, such as glue or staples, are needed to secure the bottom or cover parts together or to secure the bottom or cover to the body of the container, and for this reason, the container is very economical to manufacture and assemble. Furthermore, the container contains a very small amount of ma terial per unit of capacity.

The containers herein disclosed may be stacked together in either nested or knockdown collapsed form. In either case, the shipping and storage space required for a given quantity is very appreciably reduced. If the container is shipped knockdown "thebottom end member and cover member may also be nested, effecting further economies in shipping and storage. While paperboard or fibreboard has been specified as a desirable material, it will, of course, be appreciated that any suitable fibrous, metallic or fabricated material may be used where the condition of the material to be packaged permits of such use.
